Answer:
Considering the whole book as 100%, there’s 30% left.
Then, 30% of 230 = 0,3*230 = 69 pages.
Step-by-step explanation:
Answer:
To find a percent of the number, you need to convert the percentage into fractions or decimals. Then, multiply the fraction by the number.
Step-by-step explanation:
1. 60, 90,120,150,180,210,240,270
2. 65/100 x 200/1 = 2 x 65= 130\
3.5/100 x 180/1 = 9
Answer: The speed of the motorboat is 70 miles per hour
Step-by-step explanation: Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.
For example, at 2 hours, the distance shown on the graph is 175 miles
Subtract: 175 -35 = 140. Then divide 140/2 = 70
At 4 hours, the distance shown is 315 miles.
Subtract: 315 - 35 = 280. Then divide 280/4 = 70
70 mph is the speed.
